Sever21 [200]

Deforestation leads to fewer plants being available to conduct photosynthesis. Less oxygen is available for cellular respiration is a possible effect on the remaining plant populations.

<u>Explanation:</u>

  • Deforestation and Photosynthesis are related to each other. Because if Deforestation occurs more photosynthesis will reduce.
  • Cutting and burning down of the trees causes deforestation as it affects photosynthesis. Plants prepare food using photosynthesis.
  • The plant takes carbon-di-oxide for the preparation of food and releases oxygen. Oxygen is required for every living thing in the world.
  • As now World goes on deforestation and it should be seriously stopped.

makvit [3.9K]

Answer:

The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant.

What are the estimated allele frequencies in a population if the frequency of the dominant phenotype is 0.64 (Hint: handout to g
Nadya [2.5K]

Answer:

0.8 and 0.2

Explanation:

Hardy Weinberg law states that the allele frequency of the population remain stable from one generation to next generation if no natural selection, drift or mutation occurs in the population.

Let p and q be the dominant and recessive frequency of the population respectively.

The dominant phenotype means p² = 0.64

p = 0.8

and we known that p + q = 1, in hardy Weinberg equilibrium.

0.8 + q = 1.

q = 0.2

Thus, the dominant allele is 0.8 and recessive allele is 0.2.

Explanation:

Pastuerella multicida is a gram negative, non motile bacteria that is penicillin sensitive and belongs to the family pasteurellaceae. It is a common cause infection from dogs and cats bites.

Gram staining is a method use to distinguish and classify bacterial species into large groups which are either gram positive or gram negative.

Gram negative bacteria are bacteria that do not retain the crystal violet stain used in their gram staining while

Gram positive bacteria are bacteria that retain the crystal violet stain by their thick peptidoglycan cell wall found in them.
